'STAPLE-BEMOWR.

Application filed April 29, 1921.

Z '0 alZZ whom it may concern Be it known that 1, JOHN hllu'rn, acit-izen of the United States, residing at Non walk, county ofFairfield, State of Connecti cut, have invented an Improvement in StapleRemovers, of which the following is a specification.

This invention relates to the class of machines for fastening sheets ofpaper together that take staples in strips and drive them singly, andthe object of the invention is to provide a device by which the staplestrip can be readily removed should the machine become clogged. A.further object is to provide a device of this character that will besimple and of negligible cost, and at the same time dependable and easyto use.

In the drawing, forming a part of this specification,

Figure l is a longitudinal section of a known type of stapling machine,showing my staple remover in position to withdraw the staple strip;

Fig. 2, a perspective View of the staple remover; and

Fig. 3 is a perspective view of a staple strip.

In said drawing, 1 represents the base of a machine having pivotedthereto at one end a frame 2 by means of a pin 3. In the frame is theguide bar 4i along which the staple strip is fed to a plunger 5 whichsevere the staples singly from the strip, as in attaching sheets ofpaper together. 6 is a spring acting to hold} the plunger in the raisedor inoperative position. On the plunger is a lug or step 7 thatcooperates with a dog 8, pivoted to the frame, to feed the staple stripthrough the medium of a feed pawl 9, nor mally pressed against the stripby a spring 10.

The staple remover 11, as shown in Fig. 2, consists of a strip of metalpreferably having a thumb piece 12 at its rear end, a head 13 at itsforward end, and bent down claws 14 adjacent to the head. In operation,the remover is inserted along the top of the guide bar and above thestaple strip until the head passes under the operating end of the feedpawl a sufiicient distance to prevent the pawl from re'ngaging thestaple at the right end of'the strip. The resistance of the pawl willpress the claws tightly against the strip and. muse them to engageSpecification of Letters Patent.

Serial No. 465,366.

the device herein described to withdraw the staple strip, which may thenbe repaired or another strip inserted in its place.

It is not necessary that a bar, such as shown in the drawing be used. Itis suitici'ent if the device has a head corresponding to that shown at13 that will lift the operatin end of the feed pawl and has a claw orclaws adjacent thereto in position to take hold of the staple stripsuiiiciently to permit its withdrawal.

Having thus described my invention, I claim:

1. A device for withdrawing staple strips from a stapling machineincluding a handle adjacent one end, a head adjacent the opposite endand adapted to render the feeding mechanism inoperative, and meansadjacent said head for engaging a staple strip to be withdrawn.

2. A device of the class described comprising a bar having a thumb pieceat one end and a head at the opposite end, and means adjacent the headfor engaging a strip of staples to be withdrawn.

3. A device for withdrawing staple strips from a stapling machine havinga guide for strips of staples and means for feeding a strip of staplesalong said guide, comprising means movable along the guide in onedirection to disengage said feeding means from a strip, and movable inthe opposite direction to withdraw the strip.

4:. A device for withdrawing staple strips from a stapling machinehaving a guide for strips of staples and a pawl for feeding a strip ofstaples along said guide, comprising means movable in the same directionas the strip is fed to disengage the pawl, and movable in the oppositedirection to withdraw the strip.

5. A device for extracting staple strips from feeding position of astapling machine having a guide for strips of staples and means forfeeding a strip along said guide,

co nprising an elongated body, a head at one end thereof adapted todisengage the feeding means by movement along the guide in onedirection, and means for engaging the strip upon movement in theopposite direction.

6. A device for extracting strips of staples from a stapling machine,comprising an elongated body, having means designed to disengage thefeeding mechanism of such machine when moved along the staple strip inthe direction the strip is fed and also means to positively engage saidstrip upon movement in the opposite direction.

7. A; device of the class described comprising a barhaving means forrendering the feeding mechanism of a stapling ma chine ineflectivaand:means for engaging a strip of staples to be withdrawn.

8. A device of the class described comerisin means for renderin thefeedin C b 23 mechanism of a stapling machine ineffective,

and means for engaging a strip of staples and removing same from themachine.

9. A device for withdrawing staple strips from a stapling machinecomprising a fiat bar provided, adjacent one end, with transverselyspaced projections struck up from the bar.

10. A device for withdrawing staple strips from a stapling machinecomprising a fiat bar provided with a projection adapted to slide over astaple strip in one direction but to engage said strip and withdraw thesame when. moved in the opposite direction.

11. A device for withdrawing staple strips from a stapling machinecomprising a flat bar provided with a cut at one edge thereof, and thematerial adjacent said cutbent from the plane of the body to form aprojection to engage a staple strip.

In testimony whereof I afiix mv signature.

JOHN MUTH.
